I've reinstalled Oneiric and now the driver used to manage the device is
'brcmsmac'.
I'm not sure if this is caused by a change in the latest kernel or if my
original Oneiric installation (pre-beta) has a different setup.
However the problem is still the same:
- No wifi connection by default
- An 'acer-wireless' device is listed by 'rfkill -list'
- Blacklisting 'acer-wmi' module works around the problem
I'm changing the title to reflect this update.
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
** Summary changed:
- Conflict between acer-wmi and wl kernel modules
+ Conflict between acer-wmi and brcmsmac kernel modules
** Description changed:
I own a Lenovo Ideapad v360 laptop with a Broadcom BCM4313 wireless
network adapter. Jockey has installed "bcmwl-kernel-source" package in
order to be able to use the wireless adapter, but it doesn't work
anyway.
+
+ Note: the original problem was reported against module 'wl'. Now the problem
occurs with module 'brcmsmac'. See comment #5.
+ (Maybe the problem is not related with the module used by the device, but
with the device itself?).

NetworkManager applet displays "wireless not ready".
What caught my attention in that last command is the ''acer-wireless'' entry.
Searching on Google I found that blacklisting the ''acer-wmi'' module works
around the issue, and the wireless adapter started working. Another workaround
is to add a parameter to the ''acer-wmi'' module:
